The Gore Apparel Men's Alp X Pro Jersey uses ultra light material with strategic mesh inserts for extra breathability without weighing you down. Its plethora of pockets along the sides and back easily carry all of your energy gels, snacks, and riding accessories, allowing you to ditch the pack for extra weight savings. Its grippy back hem stays put when you're hammering up steep switchbacks and bombing down hairy sections of trail. Contrast flatlock seams provide a smooth, non irritating feel for hours of continuous comfort. Other cool features include wide elastic cuffs and an ergonomically shaped collar for enhanced comfort on the trail.
